ARTHUR A. SCHMIDT AND HERMAN F. KOLLL, F MILWAUKEE, WISCONSIN CONTAINER COVER g Application filed February 18, 1929.y Serial No. 341,002.

Our invention refers to container covers,

and particularly to that type such as described in our application for patent filed October 25, 1928, Serial No. 314,966. The object of my present invention is to providea simple construction of cover having a provision for closing and locking the same to effect an air tight seal and also to selectively release the cover. Y A further object is to provide meansV for selectively releasing the cover or to loosen the same, whereby it is held in a partially suspended position to permit Ventilating the contents of the container.

A' still further obj ect is to provide a structure of cover wherein all of the parts are Y flush with or below the top plane of the same, whereby no obstructions are presented and containers may be stacked one upon the other.V

With the above and other objects in view, which will appear as the descriptionproceeds, the invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appendedV claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the drawing, Figure lrepresents a fragmentary view of a container having a cover mechanism embodying the features-of our invention, parts being broken away and in section to more clearly illustrate structural features, and i Figure 2 is a cross detail of the same, the section being taken on the line 2-2 of Figure 1. f

Referring by characters tothe drawing, 1

40 represents a container which in this particular instance is a milk can, and the same is pro- Y vided with a reenforced neck band 2 forming the mouth thereof. The neck band is provided with a ypairvof offset guide saddles 3-3 for interlocking engagement with depending lugs 4 4, which lugs extend from a slip cover 5. The lugs in this' particular instance are part of a bar 6, which may constitute a handle for the slip cover, the said lugs and handle portion thereofv being secured to the cover in any suitable manner and being countersunk flush with the upper bead 8,'whereby no obstruction above the top edge of the cover is presented.

The guide saddles have-extending there- '55 from a pair of studs 9, which studs form pivot points for a bail 10. The shankof the bail is formed with bowedcams 11--11, the faces of 4 to thus either lock the cover in closed position, when the bail is swung into the position, as indicated in dotted lines in Figure l, or to lift the'cover slightly for ventilation, when said bail is in the position shown in full lines f the cam surfaces acting directly upon the lugs in Figure 1. l/Vhen the bail is moved into an L intermediate position, the high point a there'- of will engage the lugs 1' and thus free the'V cover from its closed position.

It is obvious that we may lock the bail in conjunction with the clip 12 when the cover l is sealed, and also, as indicated by dotted lines in Figure 1, the slip cover may in some instances be in link connection with the container neck, as indicated at From the foregoing description, it will be seen that owing to the fact that there are no obstructions above the top edge of the slip cover, cans of milk or other containers may be readily stacked one upon the other.

Furthermore, `it will be observed that when the container is used for milk orl other fluids* p whereit is desired to effect a vent, the cover can be slightly lifted so as to provide the vent, 'f

as shown in Figure 1. Thus, warm or fresh milk can be readily vented through the operation of the mechanism, while at the same time, insects or dust cannot enter the can through this vent, due to its minuteness.

We claim: v

In a container having a mouth formed by a neck-band, the combination of a slip cover therefor,`the same comprising a pair of lugs depending fromthe top edge of the cover, guide saddles carried by the neck-band and disposed beneath the edge of the cover for engagement with the lugs, a bail pivotedrto the neck-band in vertical alignment with the guide saddles, vbow-shaped cams carried by the bail for engagement with the lugs, the bow-shaped cams being provided with faces for selectively freeing the cover, partly lifting the same for venting, and for locking said cover in its closed position. f

In testimony that We claim the foregoing We have hereunto set our hands at Mil- Waulree, in the county of Milwaukee and State of Wisconsin. l ARTHUR A. SCHMIDT. HERMAN F. KOLEL I.
